[0058] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0059] Figure 1-Figure 3 FIG. 1 is a structural diagram of an electric load-carrying vehicle driving device 100 according to an embodiment of the present application. Figure 1 As shown, the driving device 100 may include:

[0060] frame;

[0061] A rotating shaft 110, the rotating shaft 110 is rotatably disposed on the frame;

[0062] A first driving assembly 120, which is disposed on the frame and is used to output a first rotation speed to drive the rotating shaft 110 to rotate; and

[0063] The second driving assembly 130 is disposed on the frame. The second driving assembly 130 is used to output a second rotation speed to drive the rotating shaft 110 to rotate. There is a speed difference between the first rotation speed and the second rotation speed.

[0064] In this embodiment, the first drive assembly 120 drives the rotating shaft 110 to rotate, and the second drive assembly 130 drives the rotating shaft 110 to rotate at the same time, so that the rotating shaft 110 performs acceleration motion, thereby reducing the kinetic energy consumed by the first drive assembly 120, so as to solve the problem of undercurrent of the first drive assembly 120. When the first drive assembly 120 drives the rotating shaft 110 to rotate alone, a reverse force is generated, thereby causing the first drive assembly 120 to heat up. The second drive assembly 130 accelerates the rotating shaft 110, increases the width of the torque of the first drive assembly 120, thereby reducing the load on the first drive assembly 120, so that the first drive assembly 120 reduces the generation of heat energy;

[0065] It should be noted that the output power of the first drive assembly 120 is greater than the output power of the second drive assembly 130, so as to ensure that the second drive assembly 130 forms an acceleration on the rotating shaft 110, and ensure that the second drive assembly 130 forms a load-reducing effect on the first drive assembly 120;

[0066] When the first drive component 120 is started and the second drive component 130 is not started, the shaft 110 rotates while maintaining the first speed. When the first drive component 120 and the second drive component 130 are started together, the second drive component 130 applies the second speed to the shaft 110, so that the shaft 110 increases the second speed under the first speed. At the same time, the current output of the first drive component 120 decreases to avoid the problem of undercurrent, and the thrust applied to the shaft 110 by the second drive component 130 is used to increase the width of the torque of the first drive component 120.

[0067] like Figure 1-Figure 2 As shown, in one embodiment, it also includes:

[0068] The gear assembly is disposed on the rotating shaft 110 , and the first driving assembly 120 and the second driving assembly 130 are both connected to the gear assembly.

[0069] In this embodiment, the first drive assembly 120 and the second drive assembly 130 jointly drive the gear assembly to rotate, so that the first drive assembly 120 and the second drive assembly 130 respectively apply the first speed and the second speed to the rotating shaft 110, so that the first speed and the second speed are superimposed.

[0070] In one embodiment,

[0071] The first driving assembly 120 includes:

[0072] A first driver 124, the first driver 124 is mounted on the frame, and an output end of the first driver 124 rotates relative to the frame;

[0073] The first gear 122 is mounted on the output end of the first driver 124 and connected to the gear assembly, and is used to output a first rotation speed to drive the gear assembly to drive the rotating shaft 110 to rotate.

[0074] In this embodiment, the first driver 124 drives the first gear 122 to rotate. Under the action of the connection between the first gear 122 and the gear assembly, when the output end of the first driver 124 rotates, the rotating shaft 110 rotates accordingly. The first driver 124 serves as a main driving member to rotate the rotating shaft 110 at a first speed.

[0075] Furthermore, the first driver 124 is a motor, and the rotation of the shaft 110 forms a push wave on the current of the first driver 124 to avoid undercurrent of the first driver 124 and heat generation.

[0076] like Figure 1-Figure 2 As shown, in one embodiment,

[0077] The second driving assembly 130 includes:

[0078] A second driver 134, the second driver 134 is mounted on the frame, and an output end of the second driver 134 rotates relative to the frame;

[0079] The third gear 135 is installed on the output end of the second driver 134 and connected to the gear assembly, and is used to output a second speed to drive the gear assembly to drive the rotating shaft 110 to rotate. The first gear 122 and the third gear 135 are gears with different numbers of teeth.

[0080] In this embodiment, the second driver 134 drives the third gear 135 to rotate. Under the action of the connection between the third gear 135 and the gear assembly, when the output end of the second driver 134 rotates, the rotating shaft 110 rotates accordingly. The second driver 134 acts as an auxiliary driving member to apply a second speed to the rotating shaft 110, and increases the second speed of the rotating shaft 110 on the basis of the first speed, so that the rotating shaft 110 forms an acceleration.

[0081] Furthermore, the first gear 122 and the third gear 135 are gears with different numbers of teeth, and the number of teeth of the first gear 122 is greater than the number of teeth of the third gear 135, so as to ensure that the first rotational speed is greater than the second rotational speed.

[0082] like Figure 1-Figure 2 As shown, in one embodiment,

[0083] The gear assembly includes:

[0084] A second gear 123, the second gear 123 is mounted on the rotating shaft 110, and the second gear 123 is meshed with the first gear 122;

[0085] The fourth gear 132 is mounted on the rotating shaft 110 , and the third gear 135 is meshed with the fourth gear 132 .

[0086] The second gear 123 and the fourth gear 132 are the same gear.

[0087] In this embodiment, the second gear 123 and the fourth gear 132 are the same gears, the second gear 123 is meshed with the first gear 122, and the fourth gear 132 is meshed with the third gear 135. Since the number of teeth of the first gear 122 is greater than the number of teeth of the third gear 135, when the second gear 123 and the fourth gear 132 are the same gears, the first speed is greater than the second speed, so as to ensure that the first driver 124 is the main accelerator and the second driver 134 is the auxiliary accelerator;

[0088] Further, the first gear 122, the second gear 123, the third gear 135 and the fourth gear 132 are all bevel gears, so that the first gear 122 is meshed with the second gear 123, and the third gear 135 is meshed with the fourth gear 132;

[0089] like Figure 2As shown, further, the gear assembly may also include only the second gear 123, and the first gear 122 and the third gear 135 are both engaged with the second gear 123, so that the first gear 122, the second gear 123 and the third gear 135 are arranged in a "C" shape, and the first gear 122 and the third gear 135 act together on the second gear 123. When the first gear 122 rotates, the first speed is applied to the rotating shaft 110 through the second gear 123, and when the third gear 135 rotates, the second speed is applied to the rotating shaft 110 through the second gear 123.

[0090] like Figure 1-Figure 2 As shown, in one embodiment,

[0091] The second driving assembly 130 further includes:

[0092] The overrunning clutch 133 is arranged on the output end of the second drive 134 .

[0093] In this embodiment, the overrunning clutch 133 is connected to the output end of the second driver 134, and the output end of the second driver 134 is connected to a second connecting rod;

[0094] When the rotating shaft 110 rotates, under the action of the fourth gear 132, the third gear 135 rotates, causing the second connecting rod to rotate. When the second connecting rod rotates, under the action of the overrunning clutch 133, the output end of the second motor remains stationary to ensure the normal rotation of the rotating shaft 110. When it is necessary to reduce the load on the first driver 124, the second motor is started to drive the second connecting rod to rotate, so that the third gear 135 drives the fourth gear 132 to rotate, and the rotating shaft 110 rotates with acceleration. Through the drive of the second motor, the first driver 124 plays a certain role in reducing the load, thereby preventing the first driver 124 from being subjected to excessive reverse force from the rotating shaft 110 during operation and causing heat.

[0095] In one embodiment,

[0096] The rack includes:

[0097] A first housing 121, an output end of a first driver 124 is rotatably disposed on the first housing 121, and a rotating shaft 110 is rotatably disposed on the first housing 121;

[0098] The second housing 131 , the output end of the second drive is rotatably mounted on the second housing 131 , and the rotating shaft 110 is rotatably disposed on the second housing 131 .

[0099] In this embodiment, the first gear 122 and the second gear 123 are located in the first housing 121, and the third gear 135 and the fourth gear 132 are located in the second housing 131, driving the rotating shaft 110;

[0100] like Figure 2 As shown, when the third gear 135 is meshed with the second gear 123 , the first gear 122 , the second gear 123 and the third gear 135 are all located in the first housing 121 .

[0101] like Figure 1-Figure 3 As shown, in one embodiment,

[0102] Also includes:

[0103] The locking assembly 140 is installed on the rotating shaft 110 and is used to limit the rotating shaft 110 from rotating in the reverse direction.

[0104] The clutch 141 is disposed on the rotating shaft 110. The locking assembly 140 is disposed on the same side of the first driving assembly 120 and the second driving assembly 130. The clutch 141 is located between the locking assembly 140 and the first driving assembly 120 or between the locking assembly 140 and the second driving assembly 130. The clutch 141 has a first state and a second state.

[0105] In the first state, the locking assembly 140 is synchronized with the rotating shaft 110 to restrict the rotating shaft 110 from reversing;

[0106] In the second state, the locking assembly 140 is separated from the rotating shaft 110 , so that the rotating shaft 110 can be reversed relative to the locking assembly 140 .

[0107] In this embodiment, the locking assembly 140 can be a backstop 143, a clutch 141 and a reverse gear 142. The backstop 143 is located at one end of the rotating shaft 110, and the clutch 141 is located between the backstop 143 and the first housing 121. The reverse gear 142 can control the driving assembly to rotate forward or reverse, and ensure that the second driving assembly 130 can provide reverse assistance to the rotating shaft 110 during the reversing process. In actual application, when the locking assembly 140 is the backstop 143, in actual circumstances, the backstop 143 can be separated from the rotating shaft 110 so that the rotating shaft 110 can be reversed relative to the backstop 143, so as to realize the switching between the forward rotation and the reverse rotation of the rotating shaft 110. When the locking assembly 140 is the clutch 141 and the reverse gear 142, the locking assembly 140 does not need to be separated from the rotating shaft 110 in the second state.

[0108] It should be noted that when the reverse gear 142 is installed on the rotating shaft 110 , the overrunning clutch 133 can be installed on the output end of the first driver 124 .

[0109] like Figure 1-Figure 3 As shown, in one embodiment,

[0110] Also includes:

[0111] A first power supply unit, the first power supply unit is electrically connected to the first driving component 120, and the first power supply unit is used to supply power to the first driving component 120;

[0112] A second power supply unit is electrically connected to the second driving component 130 , and is used to supply power to the second driving component 130 .

[0113] In this embodiment, the first power supply unit supplies power to the first drive assembly 120, and the second power supply unit supplies power to the second drive assembly 130, so as to ensure that the first drive assembly 120 and the second drive assembly 130 do not interfere with each other during use, and ensure the stable operation of the first drive assembly 120 and the second drive assembly 130;

[0114] It should be noted that the first driving component 120 and the second driving component 130 can also be controlled by the same power supply and the same controller. The two driving components share the same power supply, which easily causes the power supply to heat up.

[0115] like Figure 2 As shown, in one embodiment, it also includes:

[0116] The third driving assembly 150 is installed on the frame. The third driving assembly 150 is used to output a third rotational speed to drive the rotating shaft 110 to rotate. There is a speed difference among the first rotational speed, the second rotational speed and the third rotational speed.

[0117] In this embodiment, a third driving assembly 150 is added to the rotating shaft 110. The third driving assembly 150 may include a fifth gear 151, a sixth gear 152 and a third driver 153. The sixth gear 152 is sleeved on the rotating shaft 110. The fifth gear 151 is sleeved on the output end of the third driver 153. The sixth gear 152 is driven to rotate by the fifth gear 151 to apply acceleration to the rotating shaft 110. The output end of the third driver 153 also has an overrunning clutch 133.

[0118] Furthermore, when the first driver 124 is turned off or damaged, the second driver 134 becomes the main motor, and the third driver 153 assists the second driver 134 to accelerate the shaft body to ensure that when any one of the motors of the first driver 124, the second driver 134 and the third driver 153 is damaged, they can be switched for use;

[0119] Furthermore, by adding the third drive assembly 150 to reduce the load on the first drive 124, the load reduction effect of the first drive 124 is better. If conditions permit, multiple sets of drive assemblies can be added to increase the torque width of the first drive 124 to avoid undercurrent.

[0120] The structure of the third driving assembly 150 is the same as that of the second driving assembly 130 , with the only difference being that the number of teeth of the fifth gear 151 is smaller than that of the third gear 153 .

[0121] An embodiment of the present application provides an electric load-carrying vehicle, comprising the electric load-carrying vehicle driving device 100 as described in any one of the above embodiments.

[0122] In this embodiment, the driving device 100 can be applied to electric trucks, electric commercial vehicles, and other electric load-carrying vehicles.

[0123] The embodiment of the present application provides a working method of an electric truck driving device 100, including:

[0124] The first driving assembly 120 outputs a first rotation speed, and drives the rotating shaft 110 to rotate according to the first rotation speed;

[0125] The second driving assembly 130 outputs a second rotation speed, and drives the rotating shaft 110 to rotate according to the second rotation speed;

[0126] Among them, there is a speed difference between the first speed and the second speed.

[0127] In this embodiment, the first drive component 120 drives the rotating shaft 110 to rotate at a first speed. When the second drive component 130 is driven, the second speed is applied to the rotating shaft 110 at the first speed, which has a load-reducing effect on the first drive component 120, avoiding undercurrent in the first drive component 120, and increasing the torque width of the first drive component 120.
